' TOOL FOR BONDING RAILS.

SPECIEIOATTON forming part of Letters .Patent No. 723,270, dated March 24, 1903.

' Application filed June 15, 1901.

To all whom it may concern:

Be it known that I, SAMUEL H. HARRING- TON, a citizen of the United States, residing at NewYork city, county of New York, State of New York, have invented a certain new and useful Improvement in Tools for Bonding Rails; andI declare the following to be a 1 same, reference being had to the accompany full, clear, and exact'description of'the invention, such as will enable'others skilled in the art to which it pertains to make and use the ing drawings, which form a part of this specification.

My invention relates to. implements for bonding rails, and more particularly to an improved tool especially adapted to secure to a rail a bond of the type shown and described in my application for Letters Patent filed July 3, 1901, Serial No. 66,938.

The object of my invention is to provide a device of'the character specified which while simple in construction will efficiently secure in place the terminalv of a rail-bond.

A further object of myinvention'is to provide a bonding implement which will in one operation secure a terminal of 'a bond to a rail and also impress upon such terminal a l sign.

shank portion to which power is applied in using the device.

Reference-letter A, referring particularly to Figs. 1, 2, and 8, indicates the tool, consisting of the shank portion a and the annular enlargements e and g. findicates an annular recess separating the annular enlarge- The annular projection e is preferably made slightly smaller in diameter than the annular projection g for a purpose to be hereinafter described. The shank a is preferably tapered to conform to the Morse standard in order that itmay be readily removed from the stock or extensionpiece B. The shank a is provided with a re? duced end adapted to fit in a recess connecting the socket b and the opening 11 in the stock 13. The extension-piece or stock B is provided with a socket 1), preferably of a a die D, containing letters, figures, or other characteristi'c marks.

The operation of the embodiment of my invention shown in Figs. 1, 2, and 3 is as follows: The tubular terminal of a rail-bond having been inserted in an aperture through the rail, the end of the tool on which is formed the'annular enlargement e is placed in the tubular opening of the terminal and power is v applied to the end of the extension-piece B. The annular enlargement e is forced through the tubular terminal of the rail-bond, and thereby slightly enlarges the same. The annular recess f then passes throughthe tubular terminal without engaging the wall thereof,

such annular recess being preferably of a' width slightly greater than the width of the bond-terminal. The annular projection g being greater than the enlargement eexpands the tubular bond-terminal to a greater degree, and thereby firmly secures it within the aperture in the rail. When the enlargement g passes through the tubular terminal, the end of the extension-piece forcibly engages the face of the tubular bond-terminal and impresses thereon the letter, figure, or other characteristic mark formed on the die D.

The tool may then be removed from the stock by inserting the key 0. I

In the modified form of myinvention shown in Figs. 4 and 5, A indicates the tool the shank portion a of which is adapted to directly receive the blow or pressure necessary to force the tool through the bond-terminal. In this form of my invention, therefore, the use of the stock or extension-piece is unnecessary. The annular enlargement e is provided with radial ribs D of any desired number. The annular enlargement g is provided with similar ribs D also of any'number desired. f indicates the annular recess between the annular enlargements e g, such enlargements being preferably of unequal size, the former being slightly less in diameter than the latter.

The operation of the embodiment of myinvention shown in Figs. 4 and 5 is similar to that previously described with reference to Figs. 1, 2, and 3, except that no stock or extension-piece is used, the tool being forced through the terminal by power applied directly to the shank a. The ribs D and D form grooves or other characteristic marks within the tubular terminal of the rail-bond.

From the foregoing description it is evident that I provide a tool capable of expanding a bond-terminal within an aperture in a rail and at the same time impressing on each terminal a characteristic mark indicating that the terminal has been properly expanded in place and also indicating other information that may be desiredsuch, for instance, as by whom the bond was applied and at what date. By forming the annular projections of different sizes the bond-terminal is slightly expanded by the passage therethrough of the first enlargement on the end of the tool and is subsequently expanded to a greater degree by the passage therethrough of the second enlargement, the result being that the terminal is secured in place by the requisite expansion without being drawn through the aperture in the rail, as would be the case if a continuous engagement took place between the tool and the terminal throughout the entire passage of the former through the latter.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and a substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

What I claim as my invention is- 1. A tool for bonding rail-joints, comprising a body portion, an annular enlargement thereon, and a second annular enlargement separated from the first by an annular recess, said enlargements adapted to successively pass through and thereby expand a bond-terminal within an opening through a rail.

2. A tool for bonding rail-joints, comprising a body portion, one end of which is curved in longitudinal section, an annular projecting portion, separated from the said end by an annular recess, said curved end and projecting portion adapted to successively pass through and thereby expand a bond-terminal within an opening througha rail.

3. A tool for bonding rail-joints, comprising a bod y portion, an annular projecting portion separated from one end of the body portion by an annular recess, said annular projecting portion being curved in longitudinal section, and adapted to pass through and thereby expand a bond-terminal within an opening through a rail.
